SqlLinkCE allows the development of application that read any ODBC compliant databases, plus MS SqlServer and MS Access databases natively from a Windows Mobile device. This should allow developers to write their own synchronisation for MySql, PostgreSQL etc, as well as access these databases via TCP/IP or the cradle.
SqlLinkCE consists of a multi-threaded server process (using ADO), and is implemented on the CE device as a dll. Using the dll the developer can open databases and execute all SQL statements, returning the output back to the Windows Mobile or CE Device.
